用于缩短文本的树枝扩展? [英] Twig extensions for shortening text?

问题描述

我正在寻找的是在不破坏标签的情况下限制输出的东西.假设我有一些内容，例如来自 FCK/MCE:

What I'm looking for is something that limits the output without breaking tags. Let's say that I have some content for example coming from FCK / MCE:

<p>lorem ipsum lorem ipsum lorem ipsum lorem ipsum  </p>

<p>lorem ipsum lorem ipsum lorem ipsum lorem ipsum lorem ipsum lorem ipsum lorem ipsum lorem </p>

<p>lorem ipsum lorem ipsum lorem ipsum lorem ipsum lorem ipsum lorem ipsum lorem ipsum lorem </p>

现在，例如，如果我执行类似 {{ output|raw[:10] ~ '...' }} 我会得到:

Now for example if I did something like {{ output|raw[:10] ~ '...' }}I would get:

<p>lorem i...

但我想得到:

<p>lorem i...</p>

有什么想法可以做到这一点吗?

Any ideas how to accomplish this?

推荐答案

您应该尝试使用可用的 twig 扩展来截断 Twig & 中的文本.Symfony2.

You should try available extension of twig to truncate text in Twig & Symfony2.

您的文本是 html，因此首先使用striptags"过滤器获取纯文本，然后应用树枝的截断"过滤器.

Your text is in html so first get plain text using "striptags" filter then apply "truncate" filter of twig.

<p>{{ output|striptags|truncate(50, true) }}</p>

但首先你必须启用 Twig-Text-Extension 如下

but first you must enable Twig-Text-Extension as following

$twig->addExtension(new Twig_Extensions_Extension_Text());

或在 symfony2

or in symfony2

// app/config/config.yml
services:
    twig.extension.text:
        class: Twig_Extensions_Extension_Text
        tags:
            - { name: twig.extension }

以下是截断过滤器的可用选项

Following is available options for truncate filter

1 - 只截断

<p>{{ output|striptags|truncate(50) }}</p>

2 - 如果要保留整个单词，请设置第二个参数.

2 - Set second parameter if you want to preserve whole words.

<p>{{ output|striptags|truncate(50, true) }}</p>

3 - 如果您想使用自己的分隔符而不是..."，请设置第三个参数

3 - Set third parameter if you want use your own separator instead of "..."

<p>{{ output|striptags|truncate(50, true, ".........") }}</p>
